DOI: 10.1016/j.optlaseng.2017.01.012
Abstract: Abstract Pointwise intensity-based algorithms are the most popular algorithms in dynamic laser speckle measurement of physical or biological activity. The output of this measurement is a two-dimensional map which qualitatively separates regions of higher or… read more here.

DOI: 10.1364/ol.548001
Abstract: Dynamic speckle illumination-based quantitative phase microscopy (QPM) offers the capability to eliminate coherent noise and achieve depth selection; however, the low coherence of the illumination restricts the flexibility in objective lens selection. An asymmetric reflective… read more here.
